music library

so ive been on a kick lately. i just got a box of cds delivered today, perhaps overly old scool, but... meh. and it gave me an idea (although chances are this will go nowhere). tell me a band/musician/group ... possibly even a particular song that you feel should be in most if not all collections. if i can get a sample online, even better. if its available through my sources, I'll grab it. i guess theres not a lot of upside for you, but its something to try that isnt catfish and dicpix. im trying.
